Title: Gas turbine plants and related thermal process
IPC: F01D1/36
Filed: 1972-11-01
Abstract: 1416011 Gas turbine plant; turbines D BOLESTA 1 Nov 1972 20201/72 Headings F1G and FIT A gas turbine plant comprises a heat exchanger which is arranged to rotate and serves both as a heat exchanger by which working fluid such as air is pre-heated, and as a power generating element in the form of a turbine the driving force of which, it is stated, is the force of friction produced by the flow of working fluid therethrough also by the reaction force of fluid discharging therefrom. In one embodiment, the heat exchanger comprises a series of V-shaped tubes pointing in the direction of rotation; combustion gases from a combustion chamber are directed by inlet guide nozzles into the tube assembly which is caused to rotate, the gases discharging from the tubes on to the blades of a turbine rotor which is connected to drive a compressor. Air from the compressor is directed across the tube assembly and is thereby pre-heated being then passed into the combustion chamber into which fuel is also injected. The rotary tube assembly provides useful power. Other embodiments are described.

Abstract: 456,596. Aircraft structures ; boats ; rafts. CALVER, B. G., 52, Linver Road, Fulham, London. July 15, 1935, No. 20214. [Classes 4 and 113 (ii)] [See also Groups XVII, XIV, and XXXII] In the making of light structures, e.g. light boats, canoes, rafts and similar floating structures, aeroplane fuselage or wings, in which two sheet members have to be secured together at an angle, the two members are positioned on different faces of a wooden batten arranged in the angle between them and each is separately secured to the batten by machine driven staples of the kind sometimes referred to as wire stitches. The staples may or may not pass completely through the pieces to be joined ; if they do the free ends are clenched over. In Fig. 4, the lower batten may be omitted. The form shown in Fig. 9 is suitable for sound and heat insulating structures and cabinets, e.g. refrigerator cabinets. In this form sheets 22 and 27 may be omitted. The ends of the staples may be turned over by the method illustrated in Fig. 8, the method being particularly suitable for securing lids to boxes. According to the Provisional Specification, the end panels of a box &c. are first provided with frames or battens stapled thereto, the side panels are then provided with battens along their top and both edges, and the sides stapled to the side battens of the end panels, the bottom being then stapled to the bottom battens of the end and side panels. After filling, the top is stapled to the top battens of the ends and sides. In another form adapted for nesting the bottom projects beyond the sides, its edges taking into grooves in battens which are stapled to the outer faces of the lower edges of the sides and ends, the bottom being secured in the grooves by staples. The top of one box &c. will then nest in the bottom of another. Specification 455,088 is referred to.

Title: Processes for treating hygroscopic material
IPC: C05G3/00
Filed: 1953-07-24
Abstract: The formation of incrustations and caking on hygroscopic material, such as calcium, sodium and ammonium nitrates and table salt, is prevented by admixture with less than 1 per cent of a polymer of a vinyl compound which is polar in character such as acrylonitrile, methacrylonitrile, acrylic and methacrylic acids and their salts and esters, vinyl acetate, vinyl alcohol and vinyl pyrollidone, the polymer being formed in situ on the hygroscopic material by applying thereto the vinyl monomer which is then polymerized.  In this process the monomer may be used as such or as an aqueous solution or emulsion or as a solution in an organic solvent such as acetone, methyl ethyl ketone, methyl, ethyl, propyl, butyl and amyl acetates, benzene, toluene, xylenes, methanol and ethanol.  In an example an aqueous solution of acrylonitrile containing a mixture of ammonium persulphate and sodium bisulphite as a redox catalyst and a copper or silver salt as an activator is used.ALSO:The formation of incrustations and caking on hygroscopic material, such as calcium, sodium and ammonium nitrates and table salt is prevented by admixture with less than 1 per cent of a polymer of a vinyl compound which is polar in character such as acrylonitrile, methacrylonitrile, acrylic and metharacrylic acids and their salts and esters, vinyl acetate, vinyl alcohol and vinyl pyrollidone.

Abstract: 148,564. Jaubert, G. F. Oct. 12, 1918, [Convention date]. Oxygen; hydrogen. -In the purification of oxygen which contains a small quantity. of hydrogen or of hydrogen containing a small quantity of oxygen by passing the gas over a catalytic material, the heat liberated by the reaction is utilized for maintaining the temperature of the catalyst, thereby permitting of the use of poor contact material with little or no external heating. To this end, the electric heating-resistance 3 surrounding the catalytic material 2 is embedded in heat-insulating material 4, and the whole is enclosed in a chamber 5 provided at the bottom with a heat-regenerator comprising a nest of tubes 8. The impure gas enters by the pipe 9, passes through the tubes 8 to the catalyst 2, then circulates round the insulating-material 4 and the tubes 8, and finally leaves the apparatus by the pipe 11. The electric resistance coil is employed to raise the catalyst to the necessary temperature for starting the reaciion, and may also be required to some extent for maintaining the desired temperature of reaction.

Title: Improvements in or relating to the production of play balls
IPC: B29C67/06
Filed: 1932-07-27
Abstract: Balls, such as tennis balls, are produced by introducing into hollow spherical moulds predetermined amounts of aqueous dispersions consisting of or containing rubber, gutta percha, balata or similar vegetable resins occurring naturally or artificially obtained, such dispersions being capable of gelling on the application of heat, closing the moulds, subjecting the moulds to rotation about a variable axis and effecting total gelling of the dispersions, such gelling preferably taking place while the moulds are still in rotation.  Inflation may be obtained by providing the mould with a one-way valve through which gas at a predetermined pressure can be forced into the mould after closing and before gelling: in another modification the ball without inflation is stored in a compressed gas, subsequent leakage being reduced by treatment with a rubber solution that may also be used to secure a coating of felt or other material; in a further modification the mould is provided with a fine pointed wire carrying a filling plug that is secured to the wall of the ball and through which a hypodermic needle is subsequently inserted to permit air to be forced and also, if desired, a gas retaining p  lining, e.g. a mixture of gelatine and glycerine. Substances used for making the dispersions gel on the application of heat are sodium or potassium silicofluoride, ammonium persulphate, or mixtures such as zinc oxide and ammonium sulphate.  Specifications 219,635 and 290,313, [both in Class 70], are referred to.  In a specific example a latex mixing of the following composition is prepared: rubber (as latex) 87.7, sulphur 1.5, tetramethyl thiuramdisulphide .30, mineral oil 5, lamp black 1, and gas black .5 all in parts by weight; the mixing is cooled to about 5 DEG C. and to each 100 grams of mixing 2.4 grams of 50 per cent zinc oxide dispersion is added with 4 c.cs of a 25 per cent aqueous solution of ammonium sulphate.  The mixture is introduced into the ball mould and a capsule of paraffin containing a moist mixture of sodium nitrite and ammonium chloride also inserted; the mould is closed and placed on a rolling machine comprising two cylindrical rollers revolving in the same direction and at the same time moving backwards and forwards in opposite directions along their horizontal axes.  The mould after rotation for 15 to 20 seconds is heated by steam for two minutes and after a further period of rotation for one minute is cooled under water and opened.  The ball is dried at 45 to 50 DEG  C., placed in a mould and heated in a steam pan.  The mould is removed, cooled in water, opened and the vulcanized ball removed.
